Description

一种基于区块链的学籍追溯认证方法A blockchain-based student status traceability authentication method

技术领域technical field

本发明涉及计算机应用技术领域，具体地说是一种基于区块链的学籍追溯认证方法。The invention relates to the field of computer application technology, in particular to a block chain-based student status traceability authentication method.

背景技术Background technique

近年来，区块链（Blockchain）技术得到广泛关注和发展。区块链技术，又称为“分布式账本技术”，是一种去中心化、集体维护分布式账本的技术方案，其本质是由多个节点集体参与的分布式数据库系统。区块链不是一种单一的技术，而是多种技术整合的结果，利用区块链技术维护一个可靠的、难以篡改的账本记录，可以降低信任的风险，并能有效的降低众参与方协作的维护成本。In recent years, blockchain (Blockchain) technology has received extensive attention and development. Blockchain technology, also known as "distributed ledger technology", is a technical solution for decentralization and collective maintenance of distributed ledgers. Its essence is a distributed database system that is collectively participated by multiple nodes. Blockchain is not a single technology, but the result of the integration of multiple technologies. Using blockchain technology to maintain a reliable and difficult-to-tamper ledger record can reduce the risk of trust and effectively reduce the collaboration among participants. maintenance costs.

随着就业压力的增大，用人单位对于受聘人员的学籍学历更加看重，这也使得部分人通过学籍学历造假来谋取利益。传统的解决方案是将学籍信息通过公信网站统一发布出来，供用人单位和受聘人员进行查询。然而，这种集中存储方式容易被攻破，只需要攻破中心数据库，就能伪造学籍信息。特别是对于内部人员，可以直接接触到中心数据库，通过修改数据库内容很容易实现造假学籍信息。在这种情况下，如何有效的利用区块链技术解决学籍追溯认证问题，并且有效的保护受聘人员的学籍学历隐私成为亟需解决的问题。With the increase of employment pressure, employers pay more attention to the academic qualifications of the recruits, which also makes some people seek benefits by falsifying their academic qualifications. The traditional solution is to publish the student status information through the public trust website for the employers and employees to inquire. However, this centralized storage method is easy to be breached, and student status information can be falsified only by breaking through the central database. Especially for internal personnel, they can directly access the central database, and it is easy to falsify student status information by modifying the content of the database. In this case, how to effectively use blockchain technology to solve the problem of traceability and certification of student status, and effectively protect the privacy of the employed personnel's student status and academic qualifications has become an urgent problem to be solved.

基于此，本专利提供一种可解决上述问题的基于区块链的学籍追溯认证方法。Based on this, this patent provides a blockchain-based student status traceability authentication method that can solve the above problems.
